Answer:
x=40
Step-by-step explanation:
2x+7+x-10+63=180
3x=120
x=40
Answer: an equation that has one term which is nameless and squared also no term which gets raised to higher power.
Step-by-step explanation:
Well the probability of rolling a six on it would be 1/20.
So, if you're rolling it 1,000 times, 1,000 x 1/20 = 50.
You would roll a six approximately 50 times.

Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft
